A mixed key management scheme of clustering wireless sensor network
Yong-lei Song, Yongping Zhang · 2010
According to the existing problems in current key management strategy of wireless sensor network, which have computation complexity, multi-memory space and inflexible management, this paper proposed a mixed key management scheme of clustering wireless sensor network. Implementing the LU matrix decomposition in the cluster heads communication and Chinese remainder theorem in sensors communication, it will have less storage consumption, Lower communication and computational overhead. Under comparative analysis, it uses small storage space and supports network topology changes. Our scheme also provides the better connectivity as well as the resilience compare to current key pre-distribution schemes.
